Quality Control

Our D-Xylono-1,4-Lactone is manufactured under a strict quality management system. Each batch is tested to ensure high chemical purity and identity, with specifications suitable for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under dry, inert conditions to prevent degradation. Recommended long-term storage at 2-8°C.
